Ex-Tonic Singer Emerson Hart, Wife Have a Baby

Musician Emerson Hart and his wife Nicole have a new addition to the family – daughter Lucienne Elizabeth, born on Oct. 4, the couple tells PEOPLE.

Lucienne weighed in at 7 lbs. 11 oz., and is doing well at home in Nashville, a rep for Hart says.

Hart, 38, the former frontman for the band Tonic, talked with PEOPLE in September about the idea of being a dad – a daunting notion for a man whose own father was an abusive schizophrenic who abandoned the family 27 years ago.

"I hope my kids can always count on me," Hart said. "You have to forgive. If you don't, you carry it around. That's too heavy. I'm at peace now."

Hart worked through his issues on his solo debut, Cigarettes and Gasoline, released in July. He is currently on tour with Collective Soul and Live.

Lucienne joins a family that also includes two cats and three rescue dogs. In September, the Harts also mentioned that they were interested in adopting.
